"74HC595 Shift Register 7-Segment 8-Bit Serial-in Parallel-Out can receive (input) data serially and control 8 output pins in parallel. \r\n\r\nThis comes in very handy where do not have enough GPIO pins on our MCU/MPU to control the required number of outputs. \r\n\r\n74HC595 is often used in projects where relatively a large number of LED’s has to be controlled through the Microcontroller."
